## Object Hierarchy

## Description

E2kGlobalCatalog represents a connection to the local Active Directory Global Catalog replica. The Global Catalog is replicated at each site in a Windows domain, and contains a subset of Active Directory information for every object in the entire Active Directory tree. (As opposed to the regular Active Directory servers, which contain complete information about only the local portion of the tree.)

Connector uses the global catalog for two major purposes:

- To populate the Global Address List

- To look up information about other users, such as what Exchange server their mail is on, or what their SID is.

### e2k_global_catalog_new ()

    E2kGlobalCatalog *  e2k_global_catalog_new              (const gchar *server,
                                                             gint response_limit,

Create an object for communicating with the Windows Global Catalog via LDAP.

`server` : | the GC server name
`response_limit` : | the maximum number of responses to return from a search
`user` : | username to authenticate with
`domain` : | NT domain of `user`, or `NULL` to autodetect.
`password` : | password to authenticate with
Returns : | the new E2kGlobalCatalog. (This call will always succeed. If the passed-in data is bad, it will fail on a later call.)

### e2k_global_catalog_get_ldap ()

    LDAP *              e2k_global_catalog_get_ldap         (E2kGlobalCatalog *gc,

Returns a new LDAP handle. The caller must `ldap_unbind()` it when it is done.

`gc` : | the global catalog
`op` : | pointer to an initialized E2kOperation to use for cancellation
`ldap_error` : | set the value returned from get_ldap_connection if not NULL
Returns : | an LDAP handle, or `NULL` if it can't connect
